Laser Diodes
Sanyo and Sony — 635 nm to 830 nm, 5mW to 150mW
Laser diodes continue to find new product applications as the lasing wavelength is pushed lower into the visible
spectrum. The latest generation of Visible Laser Diodes (VLD’s) operate at or near 635nm; this wavelength being
equivalent to a helium neon gas laser, is highly visible to the human eye. VLD’s in the range from 635nm to 685nm are
replacing the traditional HeNe laser in many commercial products for good reasons: lower cost, compact size, and
superior long-term reliability. Another intrinsic benefit, laser diodes are generally better suited for battery operated
devices and other low voltage applications. Please refer to the Optima website for additional information, specifications
